How to improve the Internet on Xiaomi: an expert guide

Xiaomi smartphones, which are based on the shells MIUI and HyperOS, are famous for advanced functionality, but sometimes users face unstable connection. the situation when the network indicator shows a confident reception and pages in the browser do not load, can annoy any owner. Often the problem lies not in the hardware, but in the software settings of the system, which are optimized by default to save battery power, not for maximum speed.

Before you take a device to a service center, you need to do a comprehensive diagnostic of the software part. Aggressive energy saving optimization is the main enemy of stable connection in the background. The system can simply "strangle" network modules to save battery percentages, which leads to connection breaks during games or video calls.

In this article, we’ll look at proven methods to help reanimate mobile internet and Wi-Fi. You’ll learn how to properly configure access points, what hidden options are engineering menu worth checking, and why resetting network settings often solves the problem faster than completely flashing a device.

Diagnostics and basic network settings

The first step is to always be careful about the current status of the connection. Don't jump into complex menus if the problem is solved by simply switching modems. Redmi and Poco owners need to make sure that the settings are the right type of network. Often the phone gets stuck on EDGE or 3G, even if 4G/LTE coverage is present.

To check, go to Settings → SIM-maps and mobile networks → Preferred network type: You must select the option "Preferred" LTE" or 5G If the list is available only 2G/3G, So the communication module doesn't see the fourth generation tower, which can be related to theSIM-map and operator settings.

It is also important to check whether the flight mode is turned on mistakenly or as a result of a software failure. Sometimes it helps to "shake" modules: turn on the flight mode on the flight mode. 10-15 So you turn it off, and it causes the modem to re-register on the operator's network and get a fresh one. IP-address.

⚠️ Note: If after rebooting the communication modules icon 4G/LTE It appears, but the Internet is not working, the problem may be on the operator's side. SIM-card in another phone to exclude hardware malfunction of the smartphone.

The next important step is to check traffic limits. The MIUI shell has a built-in traffic monitor that can block network access when you reach a set limit. Go to the Security → Traffic Statistics app and make sure your main applications are not subject to strict restrictions.

Setting up APN access points

One of the most effective ways to speed up mobile internet is to manually configure APN (Access Point Name) access points. Operators often change gateway settings, and smartphones can store outdated records that slow down data transfer. Creating a new access point with current parameters often works wonders.

To get to the desired menu, go on the Settings path. → SIM-maps and mobile networks → Choose yours. SIM-map → Access points (APN). In the list that opens, click the "New Access Point" button or the plus icon. Here you need to enter the data corresponding to your operator.

The critical parameter is the APN Type field, which you need to enter the default, supl without spaces, and this parameter tells the system what the connection is used for, and in the APN Protocol field, you should choose IPv4/IPv6 to ensure compatibility with all modern servers.

Name: MTS Internet


APN: internet.mts.ru




User name: mts




Password: mts




Type of authentication: PAP or CHAP




Type APN: default,supl

Once you have entered all the options, be sure to click the menu (three dots in the corner) and select Save. Then go back to the list of access points and activate the record you just created by putting a marker next to it, and restart the device after this procedure will fix the changes.

💡

If you don’t know the exact APN settings for your carrier, call the support team or find them on the official website.Do not use the settings of third-party operators, this can lead to paid subscriptions or network failure.

Energy saving and background processes management

The aggressive MIUI Optimizer policy often causes applications to not receive data in the background, messengers may not send notifications, and the navigator may update the map, and to correct this, you need to adjust the battery for specific applications.

Go to Settings → Applications → All apps. Find the browser or navigator you use most often. Go to Saving Charge and select No Limits. This will prevent the system from "sleeping" the application process when the screen is off.

Also, you should disable the Traffic Saving feature in global settings. Path: Settings → Connection and Sharing → Traffic Saving. Make sure the switch is in the Off position. If this feature is active, the system will compress traffic through its servers, which can slow down the load of heavy sites and images.

⚠️ Attention: Disabling background activity restrictions can lead to faster battery discharge.Balance settings: leave restrictions for games, but remove them for instant messengers and email clients.

Another hidden enemy of speed is the Wi-Fi Assistant, which is designed to switch your phone to the mobile Internet if the Wi-Fi signal is weak, but in practice, it often causes permanent micro-breaks of connection. → Wi-Fi → Wi-Fi Assistant.

Shift. DNS-servers to speed up response

Slow page loading is often not due to low channel speed, but to long search. IP-server addresses. Standard DNS-Your ISP's servers may be slow or congested.Switch to public and fast DNS Google or Cloudflare significantly speeds up network response.

In modern versions of Android and HyperOS, this is done through private settings. DNS. Go to Settings. → Connection and sharing → Private DNS. The default is "Auto." Select "Host Name of provider." DNS" and enter the address dns.google or 1dot1dot1dot1.cloudflare-dns.com.

After applying the DNS settings, it is recommended to clear the DNS cache in the browser or simply restart the smartphone. You will notice that the pages begin to “drawn” instantly, even if the file loading speed remains the same, this is especially noticeable on mobile networks with unstable ping.

💡

Changing the DNS does not increase the maximum download speed, but drastically reduces the waiting time for the start of downloading (TTFB), making surfing subjectively faster.

Reset network settings and engineering menu

If software tweaks didn’t work, a radical but effective method is to reset the network settings, which will return all of the Wi-Fi, Bluetooth and mobile data settings to factory values by removing the accumulated configuration errors.

To perform the operation, go to Settings → Connection and Sharing → Reset Wi-Fi, mobile network and Bluetooth. The system will warn that stored Wi-Fi passwords will be deleted. Confirm action and wait for the communication modules to reboot.

For advanced users, you can log in to the engineering menu using the code ##4636##. In the Phone Information section, you can find the Set Preferred Network Type option. Make sure you select a mode that supports LTE (for example, LTE/TD-SCDMA/GSM).

Also in the engineering menu you can see the real strength of the signal in dBm. values from -50 to -80 dBm are considered an excellent signal, from -80 to -100 dBm - good, and everything below -110 dBm, indicates a critically weak signal, where no settings will help without an external amplifier.

Influence of covers and physical environment

The antennas in Xiaomi smartphones are often located along the frames of the case. If you use a metal case or a magnetic clasp case, it can shield the signal, significantly reducing the speed of the Internet.

Try removing the case and running a speed test. If the difference is significant, replace the accessory with a silicone or plastic one. Also note the position of the hands: "death grip," when the palm completely overlaps the bottom or top of the smartphone, can block the antennas.

In the case of Wi-Fi, the frequency range is an important factor. Routers support 2.4 GHz and 5 GHz. The 5 GHz range provides much faster speeds but less through walls. If you are far from the router, switching to 2.4 GHz can give you a more stable, if less fast, Internet connection.

⚠️ Attention: Microwave ovens operating at 2.4 GHz can create powerful interference to Wi-Fi. If the router is located near the kitchen, during heating of food, the Internet can completely disappear.
